Air Differential Pressure Switch
AFS930.8x Series
Application:
It is used to monitoring overload pressure and of the air /noninflammability/noncorrosive and differential pressure. Can be applicable to the following site:
The air filter and ventilator
The industrial refrigerating air circulation
The electric heater overheating protection
The air flow in vent pipe
The heat exchanger freeze-proofing protection
The monitoring of the pressure and level of the storage tank and pressure vessel
Model:
The air differential pressure value can be set according to adjusting the knob, no need to connect the pressure meter. Return difference controlling achieve by adjusting the “ –“ screw.
The differential pressure value indicating the vertical installing, when horizontal installing, the true value is higher 20Pa than the setting value.
